WARNING

INJECTION HAZARD

Spray from the gun, leaks or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury.

D Fluid injected into the skin is a serious injury. The injury may look like just a cut, but it is a serious

injury. Get immediate medical attention.

D Do not point the gun at anyone or at any part of the body .

D Do not put your hand or fingers over the spray tip.

D Do not stop or deflect leaks with your hand, body, glove or rag.

D Do not “blow back” fluid; this is not an air spray system.

D Always have the tip guard and the trigger guard on the gun when spraying.

D Check the gun diffuser operation weekly. Refer to the gun manual.

D Be sure the gun trigger safety operates before spraying.

D Lock the gun trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 8 if the spray tip clogs and before cleaning,

checking or servicing the equipment.

D Tighten all fluid connections before operating the equipment.

D Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

MOVING P ARTS HAZARD

Moving parts can pinch or amputate your fingers.

D Keep clear of all moving parts when starting or operating the pump.

D Before checking or servicing the equipment, follow the Pressure Relief Procedure on page 8 to

prevent the equipment from starting unexpectedly.

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

D Ground the equipment and the object being sprayed. Refer to Grounding on page 5.

D If there is any static sparking or you feel an electric shock while using this equipment, stop spray-

ing immediately. Do not use the equipment until you identify and correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid

being sprayed.

D Keep the spray area free of debris, including solvent, rags, and gasoline.

D Before operating this equipment, electrically disconnect all equipment in the spray area.

D Before operating this equipment, extinguish all open flames or pilot lights in the spray area.

D Do not smoke in the spray area.

D Do not turn on or off any light switch in the spray area while spraying or while operating if fumes

are present.

D Do not operate a gasoline engine in the spray area.

D Never use 1,1,1--trichloroethane, methylene chloride, other halogenated hydrocarbon solvents, or

fluids containing such solvents in this equipment. Such use could result in a serious chemical reaction, with the possibility of explosion, which could cause death, serious injury, and/or substantial property damage.

Consult your fluid suppliers to ensure that fluids being used are compatible with aluminum and zinc parts.

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed.

D Know the specific hazards of the fluid you are using.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

state and national guidelines.

D Always wear protective eyewear , gloves, clothing and respirator as recommended by the fluid and

solvent manufacturer.

General Information

NOTE: Reference numbers and letters in parentheses

refer to callouts in the Figs. and parts drawing.

NOTE: Always use Genuine Graco Parts and Accessories, available from your Graco distributor.

Grounding

WARNING

FIRE AND EXPLOSIO N HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE OR EXPLOSION HAZ- ARD on page 4.

1. Pump: use a ground wire and clamp as shown in Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm@) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order part number 222011 Grounding Clamp and Wire.

2. Air and fluid hoses: use only conductive hoses.

4. Spray gun or dispensing valve: ground through connection to a grounded fluid hose and pump.

5. Fluid supply container: follow your local code.

6. Object being sprayed: follow your local code.

7. Solvent pails used when flushing: follow your local code. Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

8. To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.

3. Air compressor: follow manufacturer’s recommendations.

Installation

NOTE: Reference numbers and letters in parentheses

in the text refer to callouts in the figure illustrations and the parts drawing.

The Typical installation shown on page 7 is only a guide to electing and installing required and optional accessories. For assistance in designing a system to suit your needs, contact your Graco representative.

Mount the pump to suit the type of installation planned. The pump dimensions and mounting hole layout are shown on page 17.

Pail and Drum Length Pumps

Install the pump in the drum or pail, using a suitable cover, bung adapter, or mounting clamp. The pump must be 1/2 in. (13 mm) off the bottom of the pail or drum.

The pump has a by--pass tube, route the tube back to the supply container.

NOTE: In a closed-head drum, be sure to loosen the vent plug in the drum cover to prevent formation of a vacuum.

WARNING

An accessory is required in your system: a bleedtype master air valve (A). This accessory helps reduce the risk of serious injury including injection, splashing in the eyes, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air regulator is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump.

Evenflor Automatic Pressure Control

An Evenflor air regulator installed on the pump has a Relax-A-Valve. This regulator prevents initial surging of non-atomized fluid when the gun is triggered. Air pressure in the pump is relieved automatically each time the gun trigger is released. When used with a Relax-A-Valve set in the automatic position, fluid pressure is relieved automatically also. Refer to the Evenflor Automatic Pressure Manual for additional information.

All Pumps

Install the air line accessories in the approximate order shown in the T ypical Installation drawing. A pump runaway valve (B) senses when the pump is running too fast and shuts off the air supply to the motor. For automatic air motor lubrication, install an air line lubricator (D). (For manual lubrication, see Maintenance on page 10). Install the bleed-type master air valve (A) within easy reach of the pump. Install an air regulator (E) to control air to the motor and pump speed. An air line filter (C) removes harmful dirt and moisture from your compressed air supply.

Be sure that the air supply hose is properly grounded, and is at least 1.2 in. (13 mm) ID in order to supply an adequate volume of air to the motor.

Connect a suitable grounded fluid hose and spray gun or dispensing valve to the pump’s 3/4 in. npt outlet.

The fluid drain valve (part of the Evenflo regulator installed on pump) assists in relieving fluid pressure in the displacement pump, hose, and gun; triggering the gun to relieve pressure may not be sufficient.
